These records suggest that there was much more ice on Greenland way back then, and that it has been melting for a long time.

The indication is that the Industrial Revolution of 1750 began to have an impact on the oceans earlier than previously thought.

The concept many hold today is that thermal expansion was the only game in town that caused SLC way back then.

To the contrary, the old Stockholm SLC records indicate that only about 25 years into the revolution the oceans were being impacted by global warming (induced by a maddening increase in coal burning).In Sweden's case, the SLC was sea level fall (SLF) caused by the melting of the Greenland Ice Sheet, and it is still ongoing (Proof of Concept - 5).

The take home from this information is that the Arctic ice sheets had much more volume back then, and they were and are more sensitive to global warming than we have been led to believe (The Evolution of Models - 18).

Excellent posts Dredd. I know my Biowar factors are not an exact match to SLR, but climate change does contribute to hot wars, water wars, population shifts & displacement.

Army Seeks On-Demand Mass Casualty Biologics, Chem-Bio Closure Systems U.S. Army Small Business Innovation for CBRThe U.S. Army has released new topics for potential funding via the Department of Defense FY2016 Small Business Innovation Research (SBIR) program.

On and off the battlefield, mass casualty events involving radiation exposure, chemical or biological agents, and explosive or incendiary devices can create a diverse range of injuries requiring both urgent and continuing care. Mass casualty events place enormous logistical strain on medical infrastructure, overwhelming personnel and rapidly depleting available medical supplies. This necessitates the stockpiling of medical supplies and therapeutics for on-demand use in the event of a healthcare surge.

A capability is sought to ensure off-the-shelf, large volumes of stockpiled cell and tissue biologics that would be in high demand following a mass casualty event in military theaters of operation, in humanitarian response operations, or events on the homeland.

Mark: i enjoy reading your insider contributions wherever they are. Humanity will most likely be completely extinct by 2030 (no matter what occurs in the human realm, which only adds to the death toll) due to habitat loss (no food, scarce potable water, radiation sickness and poisoning, etc).

"If all politics are local, as the saying goes, then offshore drilling is poised to put presidential candidates in the hot seat come January, when the primaries reach South Carolina.

South Carolina hasn’t voted for a Democratic presidential candidate since 1976, making it one of the reddest states in the nation, but opposition to offshore drilling is increasingly looking like a bipartisan issue."

A massive new study by 16 authors has calculated just how much ice the Greenland ice sheet has lost since the year 1900. And the number, says the paper just out in the journal Nature, is astounding: 9,103 gigatons (a gigaton is a billion metric tons).

That's more than 9 trillion tons in total. And moreover, the rate of loss has been increasing, the research finds, with a doubling of annual loss in the period 2003 to 2010 compared with what it was throughout the 20th century. [lots more]

They are still in the dark about Greenland's loss of ice prior to 1800, and worse than that, unaware of its demise even prior to 1900. when their study begins: "The fact that Greenland was losing mass throughout the entirety of the 20th century may seem surprising. But the paper suggests that we are coming out of the Little Ice Age, a cooler period, and so glacier retreat was more or less kicked off around 1900 - and then accelerated as major human-caused global warming kicked in" (quote from your link).

They would be shocked I suppose to learn it was melting a century before 1900 as the fingerprints show.

That is what SLC fingerprinting is for, to determine where the ice melted to cause SLC.

One of these daze folks will figure out that Dredd Blog is ahead of the curve, not behind it.

This Dredd Blog post you commented on asserts that Greenland was already melting circa 1774 (126 years earlier than the year 1900).

Current conventional establishment discourse has not yet contemplated that because they still do not get SLF and SLR induced by gravitational dynamics.

Dredd Blog also did the backward calculation as to ice mass increase which the post you linked to is also in error about (The Evolution of Models - 18).

Thus, they are unaware of the great quantity of ice that existed when the Industrial Revolution commenced circa 1750, or that the ice began to melt circa 25 years after the "let's burn all the coal revolution" began.

Your linked-to-post asserts that 186 GT yr is lost from Greenland now, but NASA asserts that 287 GT yr is lost now (again, from your link).
